Branch-first continuous perfusion aortic arch replacement. Insight into our results
CONCLUSIONS: BF-CPAR is safe and adds to the armamentarium of Aortic Arch Repair. In elective and uncomplicated acute-dissection cases, it has no mortality and low stroke (1.9%), and vital organ dysfunction risk. Its results which are comparable to many of the best currently reported series, is driven by avoidance of cerebral circulatory arrest and reduction of cardiac and visceral ischemic time.PMID:35238522 | DOI:10.23736/S0021-9509.22.12272-X

Impact of Cerebral Autoregulation Monitoring in Cerebrovascular Disease: A Systematic Review
AbstractCerebral autoregulation (CA) prevents brain injury by maintaining a relatively constant cerebral blood flow despite fluctuations in cerebral perfusion pressure. This process is disrupted consequent to various neurologic pathologic processes, which may result in worsening neurologic outcomes. Herein, we aim to highlight evidence describing CA changes and the impact of CA monitoring in patients with cerebrovascular disease, including ischemic stroke, intracerebral hemorrhage (ICH), and aneurysmal subarachnoid hemorrhage (aSAH). The study was preformed according to the Preferred Reporting Items for Systematic Reviews ...

De novo status epilepticus with isolated aphasia.
CONCLUSIONS: Magnetic resonance imaging findings were only subtle, and EEG was without clear ictal pattern, so the diagnosis of aphasic status remains with some uncertainty. However, status epilepticus can mimic stroke symptoms and has to be considered in patients with aphasia even when no previous stroke or structural lesions are detectable and EEG shows no epileptic discharges. Epileptic origin is favored when CT or MR imaging reveal no hypoperfusion. In this case, MRI was superior to CT in detecting hyperperfusion. This article is part of a Special Issue entitled "Status Epilepticus".

Age-Dependence of Flow Homeostasis in the Left Ventricle
Conclusions: In average, blood spends 1 to 3 beats inside the LV with very low shear stress rates. The apical region is the most prone to blood stasis, particularly in mid-aged adults. The washout of blood in the normal LV is age-dependent due to physiological changes in the degree of apical penetration of the filling waves.
Introduction
Cardioembolic stroke is a major source of mortality and disability worldwide and blood stasis one of its major determinants (Adams et al., 1986). Left ventricular (LV) function has evolved to maximize mechanical efficiency and ensure organ perfusion at a low cost of energy and fill...

127 Modifiable Cardiovascular Risk Profile in People with Mild Cognitive Symptoms Attending a Memory Service - an Opportunity to Promote Brain Health
ConclusionThis study highlights the high prevalence of unidentified or poorly controlled VRF in people with mild cognitive symptoms attending a memory service. Given its importance to brain health and mitigation of future cognitive decline, a structured focus on identifying and managing these VRF in this setting is necessary. Exercise-based lifestyle programs should be embedded in post-diagnostic services for this population.

Heart surgery and simultaneous carotid endarterectomy - 10-years single-center experience
CONCLUSION: Within the reported patient population of coronary artery heart disease and significant internal carotid stenosis, a one-time approach with CABG or heart-valve surgery and CEA is safe and feasible as justified by clinical and neurological postoperative outcomes.PMID:35841145 | DOI:10.1177/02676591221114953

Activation of Neuronal Transient Receptor Potential Vanilloid 1 Channel Underlies 20-Hydroxyeicosatetraenoic Acid-Induced Vasoactivity: Role for Protein Kinase A Inflammation and Hypertension
A rise in intraluminal pressure triggers vasoconstriction in resistance arteries, which is associated with local generation of the vasoconstrictor 20-hydroxyeicosatetraenoic acid (20-HETE). Importantly, dysregulation of 20-HETE synthesis and activity has been implicated in several cardiovascular disease states, including ischemic disease, hypertension, and stroke; however, the exact molecular pathways involved in mediating 20-HETE bioactivity are uncertain. We investigated whether 20-HETE activates the transient receptor potential vanilloid 1 (TRPV1) and thereby regulates vascular function and blood pressure. We demonstrat...

Abstract 351: Mineralocorticoid Receptor Antagonism During the Development of Hypertension Improves Cerebral Artery Endothelium Dependent Dilation Even After Treatment Withdrawal Poster Session II
Hypertension causes cerebral artery remodeling and increases the risk of stroke. Renin angiotensin system blockade during the development of hypertension has therapeutic effects even after treatment withdrawal. Mineralocorticoid receptor (MR) activation has been implicated in artery remodeling and impaired endothelial function. The possibility that there is a critical therapeutic window for MR antagonism has not been investigated. We hypothesized that temporary MR antagonism while hypertension develops would improve endothelium dependent dilation even after treatment withdrawal. Six-week-old male stroke prone spontaneously...

Regulation of myogenic tone and structure of parenchymal arterioles by hypertension and the mineralocorticoid receptor
Proper perfusion is vital for maintenance of neuronal homeostasis and brain function. Changes in the function and structure of cerebral parenchymal arterioles (PAs) could impair blood flow regulation and increase the risk of cerebrovascular diseases, including dementia and stroke. Hypertension alters the structure and function of large cerebral arteries, but its effects on PAs remain unknown. We hypothesized that hypertension increases myogenic tone and induces inward remodeling in PAs; we further proposed that antihypertensive therapy or mineralocorticoid receptor (MR) blockade would reverse the effects of hypertension. P...
